The Series 500 air quality sensor enables accurate real-time surveying of common outdoor air pollutants, all in an ultra portable handheld monitor. 

Like all of Aeroqual's handheld monitors, the Series 500 takes advantage of the unique sensor head format. Sensors are housed within an interchangeable cartridge, or “head”, that attaches to the monitor base. The head can be removed and replaced in seconds, allowing users to measure as many gases as they wish. Sensor heads feature active fan sampling which ensures a representative sample is taken and therefore increases measurement accuracy.

Other features on the Series 500 include monitor ID and location ID. Monitor ID identifies the monitor uniquely and ensures that all data from it are tied to that monitor. Location ID can be used to tag measurements to a specific location which is helpful when sampling at a number of sites over the course of a day or week.
